WASHINGTON (NASA PR) — Citizen scientists assemble! NASA’s OSIRIS-REx mission to the asteroid Bennu needs extra pairs of eyes to help choose its sample collection site on the asteroid – and to look for anything else that might be scientifically interesting.
TOKYO (JAXA PR) — The Astrophysical Journal Letters is an academic journal for research results in astronomy and astrophysics published in the United States. Our paper on the shape of asteroid Ryugu was recently included in the journal (publication date: March 26, 2019) entitled:

The Double Asteroid Redirection Test (DART) – NASA’s first mission to demonstrate a planetary defense technique – will get one chance to hit its target, the small moonlet in the binary asteroid system Didymos. The asteroid poses no threat to Earth and is an ideal test target: measuring the change in how the smaller asteroid orbits about the larger asteroid in a binary system is much easier than observing the change in a single asteroid’s orbit around the Sun. Work is ramping up at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and other locations across the country, as the mission heads toward its summer 2021 launch – and attempts to pull off a feat so far seen only in science fiction films.
PARIS, 1 May 2019 (ESA PR) — Small enough to be an aircraft carry-on, the Juventas spacecraft nevertheless has big mission goals. Once in orbit around its target body, Juventas will unfurl an antenna larger than itself, to perform the very first subsurface radar survey of an asteroid.
ESA’s proposed Hera mission for planetary defence will explore the twin Didymos asteroids, but it will not go there alone: it will also serve as mothership for Europe’s first two ‘CubeSats’ to travel into deep space.
PARIS (ESA PR) — From Earth asteroids appear as little more than dots in the sky. Europe’s miniature APEX spacecraft will operate as a mineral prospector in deep space, surveying the make-up of its target asteroids down to individual boulders, helping prepare the way for future mining missions.
I was able to capture this perspective by flying over Bennu's southern hemisphere (at about -40° latitude) while pointing PolyCam up to the far north. This frame shows Bennu from the equator all the way up to about 50° latitude in the northern hemisphere.https://t.co/VCGPMhoaaLpic.twitter.com/Dxzpd6E7Fd
PASADENA, Calif. (NASA/JPL-Caltech PR) — On April 13, 2029, a speck of light will streak across the sky, getting brighter and faster. At one point it will travel more than the width of the full Moon within a minute and it will get as bright as the stars in the Little Dipper. But it won’t be a satellite or an airplane – it will be a 1,100-foot-wide (340-meter-wide) near-Earth asteroid called 99942 Apophis that will cruise harmlessly by Earth, about 19,000 miles (31,000 kilometers) above the surface. That’s within the distance that some of our spacecraft that orbit Earth.
The international asteroid research community couldn’t be more excited.
WASHINGTON (ESA PR) — For the first time, ESA will cover a major international asteroid impact exercise live via social media, highlighting the the actions that might be taken by scientists, space agencies and civil protection organisations.
Every two years, asteroid experts from across the globe come together to simulate a fictional but plausible imminent asteroid impact on Earth. During the week-long scenario, participants – playing roles such as ‘national government’, ‘space agency’, ‘astronomer’ and ‘civil protection office’ – don’t know how the situation will evolve from one day to the next, and must make plans based on the daily updates they are given.
For the first time, ESA will cover progress of the hypothetical impact scenario from 29 April to 3 May live via social media, primarily via the @esaoperations Twitter channel. (more…)
TOKYO (JAXA PR) — Japan Aerospace Exploration Agency (JAXA) separated the SCI (Small Carry-on Impactor), which had been onboard the asteroid explorer Hayabusa2, on April 5, 2019, for deployment to Ryugu, and then put the SCI into operation.
As a result of checking the images captured by the Optical Navigation Camera – Telescopic (ONC-T) onboard the asteroid explorer Hayabusa2, we have concluded that a crater was created by the SCI.
HOUSTON (NASA PR) — Asteroid researchers on Earth will soon gain a powerful new way to remotely conduct experiments aboard the International Space Station. The device, called the Hermes Facility, is an experiment station that can communicate with scientists on the ground and give them the ability to control their studies almost as if they were in space themselves. Hermes will be carried to the space station aboard the SpaceX CRS-17 ferry flight.
Hermes is the creation of Dr. Kristen John, a researcher with the Astromaterials Research and Exploration Science (ARES) division at NASA’s Johnson Space Center (JSC). John and her research team developed Hermes as a way to study how samples of simulated asteroid particles behave in microgravity and the vacuum of space. (more…)
[CRA2] The exact size and shape of the artificial crater will be examined in detail in the future, but we can see that terrain of an area about 20m wide has changed. We did not expect such a big alternation so a lively debate has been initiated in the project!
WASHINGTON (NASA PR) — While headlines routinely report on “close shaves” and “near-misses” when near-Earth objects (NEOs) such as asteroids or comets pass relatively close to Earth, the real work of preparing for the possibility of a NEO impact with Earth goes on mostly out of the public eye.
Look at all the different types of rocks in one small area near Bennu’s south pole. You’ve got sharp rocks, fluffy-looking rocks, dark and light rocks, big and small. Over on the lower left, there are even two white rocks sitting on a dark rock. What all is going on here? 🤔 pic.twitter.com/tKmtXez9Qq
PARIS (ESA PR) — Engineers designing ESA’s Hera planetary defence mission to the Didymos asteroid pair are developing advanced technology to let the spacecraft steer itself through space, taking a similar approach to self-driving cars.
“If you think self-driving cars are the future on Earth, then Hera is the pioneer of autonomy in deep space,” explains Paolo Martino, lead systems engineer of ESA’s proposed Hera mission. “While the mission is designed to be fully operated manually from ground, the new technology will be tested once the core mission objectives are achieved and higher risks can be taken.”
